- 1RangeThe range is the difference between the lowest and highest in the numbers you get given.
example; 4, 6, 9, 3, 7
The lowest number is 3 while the highest is 9, then you take those numbers (3, 9) and take them away
example; 9 - 3 = 6 - 2MeanThe mean is all the numbers divide by how many numbers there are.
example ; 7 + 9 + 11 + 6 + 13 + 6 + 6 + 3 + 11 = 72
count how many numbers there are (not including the answer) and divide by the amount of numbers.
example; 72 ÷ 9 = 8 (the value is 8) - 3MedianIf there are two middle values, the median is halfway between them. Work out the median for this set of numbers:
3 6 6 6 7 8 9 11 11 13
There are two middle values, 7 and 8.
The median is halfway between 7 and 8, so the median is 7.5. - 4MedianThe median is the middle value.
To work out the median:
Put the numbers in order:
3 6 6 6 7 9 11 11 13
The number in the middle of the list is the median.
So the median value is 7. - 5ModeThe mode is the value that appears the most.
To work out the mode, Put the numbers in order:
3 6 6 6 7 9 11 11 13
Look for the number that appears the most. 6 appears more than any other number. So the mode value is 6.
